Abstract: ABSTRACT OF THE DISCLOSURE           An improved, multi-function, stationary-contact-and-voltage-shield structure is provided for a high-voltage gas-puffer-type circuit-interrupter, in which the surround-ing metallic shield provides a smooth, low-gradient voltage shape, collecting and cooling the dispersed hot arced gases, generated during the interrupting operation at the arc, by the provision of selectively-located venting cooling port holes provided in the metallic shield structure and also in the stationary contact structure.         The arrangement of the enveloped stationary con-tact and surrounding main stationary contact fingers, together with the outer, encompassing vented metallic shield arrangement is such as to provide an improved highly-effi-cient single-pressure puffer-type high-voltage circuit-interrupter.

Title: Explosion inhibiting potentiometer assembly and drive  mechanism therefor
Inventor: RHIND TERENCE K
IPC: H01C10/24
Filed: 1977-11-25
Granted: 1981-07-07
Abstract: ABSTRACT OF THE DISCLOSURE           .           This invention relates to potentiometer drive mechanisms, and more particularly to drive mechanisms for use with a potentiometer which must be physically isolated from the operator.  When instruments employing electrical potentiometers are operated in a volatile gaseous environment, it is very important that small explosions or electrical discharges resulting from the electrical circuitry be contained within the potenti-ometer housing to avoid severe explosions.  This problem is resolved in many cases by providing a removable housing cover which is merely taken off whenever an adjustment is made.  This procedure adds to the time needed to make an adjustment, however, and also exposes the electrical circuitry within the housing to outside contaminants.  Another approach uses a vernier screw and spring assembly to permit adjustments to be made from the outside, but only a somewhat coarse adjustment can be achieved with this method, and the vernier is subject to overstressing at the opposite limits of potentiometer rotation.  According to the present invention, a potentiometer contained within a housing is operated from the outside by means of an operating member which extends inward through an orifice in a housing wall.  The operating member engages the potentiometer drive stem with the aid of an O-ring slip clutch to prevent overstressing and includes a flange which is spring-urged against the interior housing wall to inhibit internal explosions from propagating to the outside.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for continuously measuring a gradient of a curved surface at a number of different points thereon is disclosed in which a laser beam reflected at the point to be measured on the surface makes a beam spot on a photo sensor.          The photo sensor follows the beam spot while  the center of the beam spot and the center of the photo sensor coincide.  The displacement between the beam spot from the point subjected to measurement and the beam spot from a reference point on the sur-face or the photo sensor is proportional to the gradient at the point subjected to measurement.  The photo sensor is, for example, a differential type which comprises four photo diodes.  The numerical control table is used to determine the positional relationship of the point to be measured with respect to the laser beam, and an X-y recorder is used to follow the beam spot.

Abstract: APPARATUS FOR ADJUSTING THE POSITION OF AN ARM IN A RECORD PLAYING DEVICE, SUCH AS A PHONOGRAPH OR THE LIKE                    ABSTRACT OF THE DISCLOSURE     Apparatus for controlling an arm of a record player of the type having a base, a turntable upon which a record disc rotates, a pivot support extending upward from the base for sup-porting the arm and about which pivot support said arm pivots in a plane perpendicular to the surface of the record disc, and a transducer at one end of the arm for scanning the record disc.          Pivotal movement of the arm is detected and a position signal is produced to represent the angular position of the arm.  A detect-ing circuit detects when the position signal differs from a pre-determined reference signal, this difference corresponding to an angular displacement of the arm, to produce a control signal.  A drive device is coupled to the pivot support and is responsive to the control signal for driving the pivot support in a direction perpendicular to the surface of the record disc so as to reduce the angular displacement of the arm and thereby adjust the posi-tion signal until it is equal to the predetermined reference level.                             -i-

Abstract: IMPROVED VALVE APPARATUS AND    METHOD OF MAKING SAME          Abstract of the Disclosure A valve apparatus is integrally molded from an elastomeric material so as to form a valve seating portion including a valve opening, a valve member and connective strands extending from the valve seating portion to the valve member.  The valve member is initially molded on one side of the valve opening, and a portion of the valve member is passed through the opening to the other side thereof.  The connective strands are stretched while passing a portion of the valve member through the opening so as to create a bias on the valve member which tends to seat the valve member on the other side of the opening.  The valve apparatus is useful to close one end of a serum separator tube which is inserted into a serum collection tube.  The stretched connective strands bias the valve member closed when the serum separator tube is stationary within the collection tube.  Alternatively, the valve apparatus is useful when employed as a portion of a plug-like piston in a collection tube.  The tube is placed on a centrifuge and the plug seeks the interface between the light phase and the heavy phase of the blood.  In doing so, the plasma passes through the valve apparatus which closes after centrifugation has been com-pleted.

Abstract: ABSTRACT OF THE DISCLOSURE         A tuning system for a television receiver includes fine tune memories and tuning information memories having ref-erence channel nominal tuning information for each frequency band and increment tuning information representing the tuning voltage differences between successive channels.  Accumulator means add the reference channel tuning information and incre-ment information to develop the nominal tuning voltage for any selected channel.  Control logic, including channel number counters and latches and state counters, is coupled to the accumulator means, tuning information memories and the fine tune memories.  The memories' and accumulator means' outputs are coupled to a corresponding plurality of comparators which are also coupled to counters for deriving pulse-width modulated (PWM) signals corresponding to tuning information in the accu-mulator means and memories.  The PWM signals are supplied to a tuning voltage generator where they are combined to produce the final tuning voltage for the tuner.  The increment tuning information is representative of the slope of the tuning curve at each of the channel tuning points and is used to equalize any auxiliary tuning voltage source.  The final tuning voltage consists of the derived nominal tuning voltage combined with the product of the fine tune voltage and channel increment tuning information.
